CVE-2022-43308Public exploitNetwork attack vector

Guest-to-Administrator escalation via unchecked user creation

Published Nov 18, 2022 · Updated Apr 30, 2025

Privilege escalation in Intelbras SG 2404 MR 20180928-rel64938 allows remote authenticated users to create Administrator accounts. The /userRpm/UserManageRpm.htm handler accepts a guest session token in tid and processes type=add with usertype=1 without enforcing the administrator-only authorization boundary. A guest account is required; successful exploitation creates a new administrator credential with full switch-management access.
